WebThe square of 2 is 4, so if the radius doubles the area is multiplied by 4. This is the example given in the video. If the radius triples, that's a factor of 3. The square of 3 is 9, so if the radius triples the area is multiplied by 9. You can see this goes up rather quickly: multiply the radius by 5, and the area is multiplied by 25.
